摘要研制了一种基于微型四传感器热线探针的速度测量系统，该系统能够在很宽的流动角范围内同时测量三分量。 校准技术允许在探头的整个接收锥中进行测量，而不受与分析角度响应方程相关的误差的限制。该技术基于具有趋于缓慢变化的值的查找表，允许使用简单的插值方案。在湍流管流中的测量验证了该技术的准确性。
Abstract A velocity measurement system based on a miniature four-sensor hot-wire probe capable of simultaneous three-component measurements throughout a wide range of flow angles has been developed. The calibration technique allows measurements to be made throughout the acceptance cone of the probe without being restricted by the errors associated with analytic angle response equations. This technique is based upon look-up tables with values which tend to vary slowly, allowing a simple interpolation scheme to be used. Measurements made in a turbulent pipe flow verify the accuracy of the technique.
